Is the temperature gauge of your BMW engine staggering higher than usual when you are idling in traffic or ascending a steep incline? If so, your BMW has probably developed an overheating issue that may require professional intervention. When your BMW overheats, it could lead to damage to your engine. So, what makes a BMW overheat and how should you deal with it correctly?
Reasons for BMW Overheating
- Low Coolant: Low coolant level is one of the most frequent reasons for overheating the engine in a BMW. A coolant, which is also referred to as antifreeze, plays a role in controlling the temperature of the engine. If there is little or no coolant, the engine can become hot very easily. You should always check the level of the coolant in your car and add more if needed.
- Faulty Water Pump: The water pump is that part of your BMW engine that circulates coolant through the engine to cool it. If the water pump seizes or is not performing its job right, the coolant won’t circulate and the engine will overheat. It is also possible for a leaking water pump to cause overheating in your BMW.
- Radiator Issues: The radiator assists in removing heat from the coolant before the coolant is pumped back into the engine. In the process of doing its work, radiators can get dirty which can lead to clogging. It is also possible for it to develop leakage problems. If the radiator is unable to cool the fluid properly, then the engine is prone to overheating. This problem can be solved by strictly following the planned maintenance and inspections.
- Thermostat Failure: The thermostat allows coolant to flow through the engine by opening and closing when it should. If it stays in the closed position, the coolant will not be able to pass through and your BMW will overheat because there is not enough fluid to keep it cool. As soon as you notice that it is not working properly, take it to your mechanic so that it can be changed and the right amount of coolant is circulated.
- Fan Malfunctions: The cooling fan works when your engine is running and helps to ensure the coolant is cooled when the car is at a standstill or in slow motion. If the fan is not working as it is supposed to, there may be an inadequate supply of fresh air and the engine may overheat.
How You Can Address BMW Overheating
- Check Coolant Levels: The first check that needs to be carried out is to look at the state of the coolant in the coolant recovery tank. If you find the coolant level low, then add more coolant and make sure it is the right mixture of water and antifreeze. This container is usually under pressure, so it is advised to allow the engine to cool before the reservoir cap is opened.
- Inspect for Leaks: Take time and check around the radiator, the hoses, and the water pump for symptoms of coolant leakage of coolant. If you see any fluid around or under your BMW, it could mean a leakage that needs to be repaired.
- Check the Radiator and Fan: You can check for signs of blockage or mechanical damage to the radiator through physical examination. If the car fan does not come on, it may be a problem with the fan motor or a sensor that controls the fan. This task should be left to a professional mechanic who can diagnose and repair the problem.
- Visit a Professional: If you cannot find out the reason for the overheating or if the problem does not go away after you try different solutions, it would be best to take your BMW to an auto repair shop. A skilled mechanic can come in to conduct a complete diagnosis and repair the problem before the engine is severely harmed.
